What is their rationale claiming that a connector rated for max 13 amps is enough to draw over 200 watts at 12 volts? I know my Ohm's law, and I can multiply 12 volts times 13 amps, which comes out to 156 watts. One cube draws over 20 amps I think. The heat generated is proportional to the square of the current. 20^2 / 13^2 = 2.37, which means 137% more heat than the connector is rated for.
